, other temperature indicating devices to be ill] formed integral with or removably locked on the radiator cap or neck.

At the present time, the conventional radiator construction is to have a core or cooling section separate from and fastened to an outer shell. The core is provided at itstop with a neck, permanently fastened thereto,*for the purpose of filling the core with a coolingmedium. The usual method of fastening the core into the shell is by bolts or other means so that should it become necessary to repair or replace the core,the core can be removed from the shell by removing the cap from the neck and unfastening the bolts so that the shell can be pulled outwardly'from the bottom of the core and then raised upwardly until thetop of the shell is lifted sufficiently high to clear the top of the neck which extends through anopening in the top of the shell.

In providing a theft-proof radiator neck cap it has been necessary heretofore to incorporate in it some device that will facilitate the removal of the cap from the neck, when it becomes necessary to remove the shell for purposes of repair or replacements 'of the core. 7 The removal of these theft-proof radiator neck caps is'at times an inconvenient, tedious and difficult operation. With the present day type of radiator construction the radiator caps must be removed before the shell can be lifted from the core, because the caps are larger than the opening in the top of the shell and consequently will not pass through such opening. I Objects of the invention are the provision of a radiator constructed so that such theftproof radiator caps may be securely locked on the neck of the radiator, or formed as an 7 integral part of the neck; the provision of a construction which will permit ornamental or other devices to be formed integral with the neck or cap; the provision of a'construction which will permit temperature indicating devices extending above the top of the neck or cap to be securely locked on said neck or formed as an integralpart of the neck or 1924.

cap; the provision of a construction, in which the neck is detachable from the core and shell to permit removal of the core from the shell for purposes of repair'and replacement; the arrangement of the parts in such a construction so that the neck will be locked against removal while the parts are in assembled position, such arrangement permitting the removal of the neck only upon partial detachment of theshell from the core and such other 1 objects and advantages of the invention as may be found to obtain in the structure herelnafter set forth and claimed.

On 'the drawings, 10 is theradiator shell having upwardly extending sides 11 and 'a curved top 12. Brackets 13 having apertures 14 therein are provided at the lower portions of the sides 11 to secure the shell to similar brackets on the core. The top 12 0f the shell is provided with anopening 15, shown as circular in Figs. 1 to 5 and as elliptical in Figs. 6 to 9, portions of the material about the circular opening in Figs. 1 to 5 are cut away to provide'slots 16 in the shell which receive In the accompanying drawings, formin a V projections on the neck. The core or cooling section 17 is formed separate from the shell and is provided with brackets 18 at the lower portions of its sides, said brackets having apertures which register with the apertures in the brackets 13 and through which means may pass to secure the core within the shell. The bottom 19 of the shell is provided with bolts 20 that also serve to kee the shell in proper position on the core. he top 21 of the core is provided with an aperture 22 and extending upwardly from this opening isa collar 23 which is permanently clinched at 24 to the material about the aperture 22 in the top 21. At its upper end the collar is threadedv on its outer surface 25 to receive the threaded lower end 26 of theremovable radiator neck 27 so that the neck can be removably secured on the core, and in order to prevent possible leakage through the joint between the portions 25 and 26 there is provided, atthe lower end 26 of the removable radiator neck a gasket 28. The cylindrical neck, illustrated in Figs. 1 to 5, has projections that fit into the slots 16 when the shell is in normal assembled position, said projections having holes for the reception of the ends of a holding down bail30. The projections 29 extend from the bottom of the neck to a point 31 short of the top of the neck so that when the bail is withdrawn from the projections 29 and the shell is unfastened at the bottom and swung out, as indicated in dotted lines in Fig. 2, it can be raised over the core until the top of the shell clears the top of the projections, thereby releasing the neck from the shell with sufficient clearance to permit unscrewing of the neck from the collar on the core. A filler opening cap 32 is hinged to the front 33 of the upper end of the neck, said cap having a curved slot 34 providingacam surface 35 upon which the bail rides to hold the cap tightly down in the top of the neck to close the filler opening. The cap is provided with an inclined outer seating surface 36 which rests on a gasket 37 supported by the seat 38 formed integral with the-neck.

Referring to Figs. 1 to 5, there is shown a frame 40 extending from the top ofthe neck, said frame being cast integral with the neck. Secured within the frame 40 is a temperature responsive element 41 that extends into the space beneath the top 42 0f the neck. The element 41 is protected at its lower end 43 by a metallic tube 44. that is closed at the bottom by a screw plug 45. The upper portion of the element 41 is protected by a metal protector plate 46 and a glass protector 47. The metal plate 46 is provided with an opening 49 to facilitate the visibility of action of the temperature responsive element 41.

Referring to Figs. 6 to 9, there is shown an embodiment of the invention in which the hinged cap is secured to the neck to cover the opening in the front of the top of the neck, and to the rear of this cap is provided a closure member 50 having a screw thread- 7 ed opening 51 through which the stem 51 of a removable temperature indicating device extends. on the stem beneath the member 50 and secured within the top surface of the member 50 is a plug or set screw 53 pointed at its'top. and extending slightly above the top surface of the member 50 so that when the nut 52 is tightened it will draw the flange 54, of the portion of the temperature indicating device that extends above the top ofthe neck, down on the member 50 so that the temperature indicating device cannot be unscrewed from the top but only from the under side of the neck. In the embodiment illustrated in Figures 6 to 9,.the neck is formed elliptical at its lower portion as shown at 55, while its inner lower surfaces are cylindrical as indicated at 56. The elliptical portion 55 terminates at its upper end in an inclinedannular portion 57 which is integrally connected witha. vertically extending cylindrical portion 58 of the neck. When the radiatorv illustrated in Figs. 6 to 9 is in assembled position, the elliptical portion 55 of the neck is enclosed in the elliptical opening 59 of the shell and is locked therein by the securing of the shell on the core, and while so locked in position the neck proper can not be unscrewed from the core by reason of'the shape of the opening in the shell and the lower portion 55 of the neck. To remove the neck, the shell must be unfastened from the core and raised up wardly thereon until the opening in the shell is above the top 60 of the elliptical portion 55 at which point the neck can be readily rotated and unscrewed from the collar and then lifted out of the shell. After the neck is so removed from the shell the nut 52 can be unscrewed and the temperature indicating device removed.

To assemble the radiator constructed in accordance with Figs. 1 to 5, the ends of the bail are withdrawn from the project-ions 29 and the neck then inserted through the opening in the top of the shell until the top of the projections 29 are beneath the top of the shell,

then the neck isscrewed tightly down on the collar. Aft-er the neck is screwed on the col.-

A locking nut 52 is threaded lar the shell is lowered until the slots fit around the projections 29, then the shell is fastened on the core and the ends of the bail inserted in the projections 29. j

To remove the core from the shell, the ends of the bail are withdrawn from the projection provides an arrangement in which such a device can extend upwardly from the top of the neck and be formed as an integral part 7 of the neck or cap; and the neck or cap can be removed only after the shell and core are detached from each other ;that an ornamental cap or other devices can be locked permanently to the neck or formed as an integral part of the cap or neck and yet permit removal of the shell from the core without detaching such devices or the ordinary theftproof cap from the neck. A

The invention as hereinabove set forth is embodied in a particular form of construction but may be variously embodied'within the scope of the claims hereinafter made.

Those features of the invention exemplified in the foregoing description which relate broadly to the locking of a removable neck in position by the shell when assembled on the core and to the removal of the neck onlywhen the shell is detached or partially removed from the core are made the subject matter of my copending application for Letters Patent of the United States, filed July 16, 1924:, Serial No. 726,236.
